获取相应的dateTime最大值时出错

Question

Table 'test'

+------+--------------------+
|value |    dateTime        |
+------+--------------------+
|19    |2011-12-22 11:09:42 |
+------+--------------------+
|16    |2011-12-22 05:09:00 |
+------+--------------------+
|2     |2011-12-22 07:09:42 |
+------+--------------------+
|30    |2011-12-22 10:09:15 |
+------+--------------------+
|45    |2011-12-22 03:09:42 |
+------+--------------------+

I would like to get the Max value and its corresponding dateTime. In this case, the final result should be: max value:45 and dateTime:2011-12-22 03:09:42 . I used

SELECT MAX( `value` ) , `dateTime`
FROM `test`

After running the above sql statement, the max 'value' is correct (ie 45), but the 'dateTime 'is not correct (ie2011-12-22 11:09:19)

Is there anyone can help me? Many thanks!

Answer 1

try this:

SELECT TOP 1 `value`, `dateTime`
FROM `test`
ORDER BY `value` DESC

Answer 2

-- general
select *
from test
where value= (select max(value) from test)

or

--tsql
select top 1 *
from test
order by value desc

or

--mysql
select *
from test
order by value desc
limit 1;

There is a bug in MySQL in version 5.5. Try upgrading MySQL. Your code is not the problem.
